yum install squid -y 安装服务
vim /etc/squid/squid.conf
56 http_access allow all 允许所有访问
62 cache dir ufs /var/spool/squid 100 16 256
systemctl start squid 开启服务
测试172.25.49.11
打开 firefox 把Advanced——Network中的Settings,Manual ~ 中 写入你所访问的缓冲机（有两块网卡的那个）。
然后访问172.25.254.250，就会成功。虽然 ping 不同 172.25.254.250,但是能访问。
